Naked-eye visualization of geometric frustration effects in macroscopic spin ices


Abstract in English

We study planar rectangular-like arrays composed by macroscopic dipoles (magnetic bars with size around a few centimeters) separated by lattice spacing a and b along each direction. Physical behavior of such macroscopic artificial spin ice (MASI) systems are shown to agree much better with theoretical prediction than their micro- or nano-scaled counterparts, making MASI almost ideal prototypes for readily naked-eye visualization of geometrical frustration effects.
