Fig. 1: Pressure effect on metal-organic magnets LCPC and KCPC.

a The crystal structure of LCPC or KCPC shows the layered structure. b A representative TEM image of KCPC magnet indicates a 2D structure. c Comparison of the coercivity coefficient of inorganic and organic magnets presents the large tunability in LCPC and KCPC magnets under pressure. The coercivity coefficient is defined as the pressure derivative of the magnetic coercivity (dHc/dP).
