Building a better SQUID: A prototype for a SQUID-like magnetometry device for the indirect detection of room-temperature switching in spin-crossover nanoparticles has been developed and used in the study of [Fe(hptrz)3](OTs)2 (hptrz=4-heptyl-1,2,4-triazole, OTs=p-toluenesulfonyl) nanoparticles, as a proof of concept for this novel micromagnetometry approach. The method provides significant benefits over conventional SQUID and nano-SQUID techniques.
