WebJul 28, 2014 · At a temperature of absolute zero, the local magnetic moments align to produce the strongest possible magnetic force in a magnet. As temperature increases, a magnet becomes weaker as more local magnetic moments spin away from the shared alignment; a magnon population is created with this elevated temperature. WebApr 15, 2013 · The effect is considerably stronger for the gadolinium alloy Gd5 (Si2Ge2). Praseodymium alloyed with nickel (Pr Ni 5) has such a strong magneto caloric effect that it has allowed scientists to approach within one thousandth of a degree of absolute zero.
