Spanish researchers have designed what they believe to be a new type of magnetic cloak, which shields objects from external magnetic fields, while at the same time preventing any magnetic internal fields from leaking outside, making the cloak undetectable. The development of such a device, described as an 'antimagnet', could offer many beneficial applications, such as protecting a ship's hull from mines designed to detonate when a magnetic field is detected, or allowing patients with...

New theory of 'Extremely Correlated Fermi Liquids' may explain anomalous photoemission spectra of high-temperature superconductors Although high-temperature superconductors are widely used in technologies such as MRI machines, explaining the unusual properties of these materials remains an unsolved problem for theoretical physicists. Major progress in this important field has now been reported by physicists at the University of California, Santa Cruz, in a pair of papers published...

Discovery in parent of one high-temperature superconductor may lead to predictive control A team of scientists studying the parent compound of a cuprate (copper-oxide) superconductor has discovered a link between two different states, or phases, of that matter - and written a mathematical theory to describe the relationship. This work, appearing in the July 22, 2011, issue of Science, will help scientists predict the material's behavior under varying conditions, and may help explain how it's...

Berkeley Lab's Advanced Light Source uncovers colossal conductivity changes in a special material If there were a Hall of Fame for materials, manganites would be among its members. Some manganites, compounds of manganese oxides, are renowned for colossal magnetoresistance "“ the ability to suddenly boost resistance to electrical conductivity by orders of magnitude when a magnetic field is applied "“ and manganites are also promising candidates for spintronics applications "“...

In the search for superconductors, finding ways to compress hydrogen into a metal has been a point of focus ever since scientists predicted many years ago that electricity would flow, uninhibited, through such a material. Liquid metallic hydrogen is thought to exist in the high-gravity interiors of Jupiter and Saturn. But so far, on Earth, researchers have been unable to use static compression techniques to squeeze hydrogen under high enough pressures to convert it into a metal. Shock-wave...

In recent years, UC Santa Barbara scientists showed that they could reproduce a basic superconductor using Einstein's general theory of relativity. Now, using the same theory, they have demonstrated that the Josephson junction could be reproduced. The results are explained in a recent issue of the journal Physical Review Letters. The Josephson junction, a device that was first discovered by Brian David Josephson in the early 1960's, is a main ingredient in applications of superconductivity....

It has been 100 years since the discovery of superconductivity, a state achieved when mercury was cooled, with the help of liquid helium, to nearly the coldest temperature achievable to form a superfluid that provides no resistance to electrons as they flow through it. During that century, scientists have struggled to find a precise mathematical explanation of why and how this strange fluid behaves as it does. Liquid helium-4 itself becomes a superfluid when cooled to within a few degrees of...

Bubbles are blocking the current path of one of the most promising high temperature superconducting materials, new research suggests. In a study published today, Monday, 16 may, in IOP Publishing's journal Superconductor Science and Technology, researchers have examined bismuth strontium calcium copper oxide (Bi2Sr2CaCu2Ox, Bi2212) "“ one of the most promising superconducting materials capable of creating large magnetic fields way beyond the limit of existing magnets "“ and found...

An electromagnet, a magnet whose magnetic field is produced by the flow of electric current, works until the electric current ceases. The magnetic field in a simple electromagnet is created by a wire passing through it with an electric current. The strength of the magnet depends on the amount of current. By making the wire into a coil the magnetic field is concentrated. A straight tube coil is a solenoid. A stronger magnetic field can be produced by putting a ferromagnetic material, such as...
