V septembri 2006 boli inštalované v novom spoločnom laboratóriu ÚEF SAV a PF UPJŠ aparatúry PPMS and MPMS od firmy Quantum Desing. PPMS umožní merania termodynamických a transportných vlastností v magnetických poliach do 9 T a MPMS umožní DC a AC magnetické merania v poliach do 5 T a vo veľmi nízkych poliach.
