sciencehabit writes "Most magnets shrug off tiny temperature tweaks. But now physicists have created a new nanomaterial--an ultrathin 10-nanometer layer of nickel grafted onto a 100-nanometer-thick wafer of a substance called vanadium oxide--that dramatically changes how easily it flips its magnetic orientation when heated or cooled only slightly. The effect, never before seen in any material, could eventually lead to new types of computer memory."
