Pressure effects on single chain magnets

Abstract Pressure effects on a single chain magnet [Mn 2 (saltmen) 2 Ni(pao) 2 (py) 2 ](ClO 4 ) 2 (saltmen 2− = N , N ′-(1,1,2,2-tetramethylethylene)bis(salicylideneiminate), and pao − =pyridine-2-aldoximate) have been investigated through AC magnetic measurements under pressure ( P ). The slow relaxation of the magnetization depends on pressure. Both the blocking temperature ( T B ) and energy barrier ( Δ ) increase by pressurization, and those enhancements saturate at around P =7 kbar.
