Question

can anyone tell me about the thermal and magnetic properties of neodymium magnet at low temperatures (around 70K) and some plots, graphs if available...

Answer 1

Refer here: http://en.wikipedia.org/wiki/Neodymium_magnet
Look at the table titled "Physical and Mechanical Properties"

Pay special attention to Temperature coefficient of remanence, and Temperature coefficient of coercivity
