It was recently predicted that, in addition to well-known spinon excitations, a 1D spin-trimer chain with periodic exchange couplings hosts novel composite excitations. Bera et al. experimentally demonstrate and characterize such excitations, termed

Growth of Co film on SiO2/Si substrates with surface roughness of 0.5 nm and 1.6 nm have been studied in-situ using magneto-optical Kerr effect (MOKE) and transport measurements. In-situ measurements jointly suggest that the films grow via Volmer-Web

A combined role of structure and morphology of polycrystalline Fe thin films in the evolution of uniaxial magnetic anisotropy (UMA) subjected to several cycles of the ion beam erosion (IBE) process...
The artificial tailoring of magnetic anisotropy by manipulation of interfacial morphology and film structure are of fundamental interest from application point of view in spintronic and magnetic memory devices. This letter reports an approach of engi

Experimental detection of spin dynamics of the quantum spin liquid phase, which occurs when the quantum fluctuations lead to fractionalized spin states, remains a challenge. In this paper, we illustrate spin-liquid signatures in the geometrically fru
