Abstract

Graphical abstract Bimetallic ferrimagnet [Cr(CN) 6][Mn( R)-pnH(H 2O)]H 2O with crystallographical chirality exhibits a giant third-order harmonic susceptibility χ 3 ω at around 38 K. This giant nonlinear magnetic response was drastically suppressed even by slight strain, whereas the traces could be confirmed in the region up to 5.3 kbar. We conclude that the appearance of the giant nonlinear magnetic response requires crystal chirality well-regulated over the crystal. Highlights ► Bimetallic ferrimagnet [Cr(CN) 6][Mn( R)-pnH(H 2O)]H 2O with crystallographical chirality exhibited a giant third-order harmonic susceptibility χ 3 ω at around 38 K. ► The existence of the third-order harmonic response could be confirmed even under uniaxial stress, corresponding to the hydrostatic pressure of 3.7 kbar. ► The magnitude of the characteristic third-order harmonic response was drastically suppressed by slight strain.
