“…In contrast, the negative exchange interaction between the core and the shell also leads to the appearance of multiple loops. Similar behaviors can be seen in previous studies of nanowires, [
32,61–63 ] ferrimagnetic nanoisland, [
64 ] multilayer, [
65 ] and the
/YMnO
antiferroelectric/ferroelectric Ising bilayer system. [
66 ] Experimentally, triple and double hysteresis loop behaviors have been witnessed in nanoparticles, [

,
,
,
, and
multilayered nanowires.…”
