Magnetic charge crystals imaged in artificial spin ice

A team of scientists has reported direct visualization of magnetic charge crystallization in an artificial spin ice material, a first in the study of a relatively new class of frustrated artificial magnetic materials-by-design ...

Chameleon pulsar baffles astronomers

A pulsar that is able, without warning, to dramatically change the way in which it shines has been identified by an international team of astronomers.

Evidence of second fast north-south pole flip found

(PhysOrg.com) -- The Earth's magnetic poles flip around every 200,000 years or so, with north becoming south and vice versa. Normally, the process takes 4-5,000 years and it ought to be impossible for the flip to be much ...

New theory for magnetic stripes on Mars

(PhysOrg.com) -- A controversial new theory has been proposed to explain a series of stripes of permanently magnetized minerals containing iron in the Martian crust. The magnetized stripes, which have alternating orientations, ...

Physicsts reveal how to cope with 'frustration'

For most people, frustration is a condition to be avoided. But for scientists studying certain "frustrated" ensembles of interacting components - that is, those which cannot settle into a state that minimizes each interaction ...

Researchers suggest new memory storage mineral

(PhysOrg.com) -- Researcher Derek Stewart says the mineral kotoite could be an ideal insulator for memory storage devices called magnetic tunnel junctions.
