Magnetic semimetals carry a great promise for potential applications in novel spintronic devices. Nevertheless, it is a challenging topic to realize the tunable topological states by the magnetism in a controllable way. Here, we report novel magnetic

Particles with a superparamagnetic cobalt inner core, silica outer core, and covalently bound homopolypeptide shell were investigated under thermal and magnetic stimuli. The homopolypeptide was poly(ε-carbobenzyloxy-l-lysine), PCBL, which is known t

The control of domain walls is central to nearly all magnetic technologies, particularly for information storage and spintronics. Creative attempts to increase storage density need to overcome volatility due to thermal fluctuations of nanoscopic doma
