Dimensional reduction by geometrical frustration in a cubic antiferromagnet composed of tetrahedral clusters
Ryutaro Okuma, Maiko Kofu, Shinichiro Asai +10
Dimensionality is a critical factor in determining the properties of solids and is an apparent built-in character of the crystal structure. However, it can be an emergent and tunab…
Nontrivial temperature dependence of magnetic anisotropy in multiferroics BaMnGeO
Shunsuke Hasegawa, Shohei Hayashida, Shinichiro Asai +3
We measured the temperature dependences of the static magnetization and the spin excitation in a square-lattice multiferroics BaMnGeO. An anisotropy gap of the observed…
Spin-gap formation due to spin-Peierls instability in -orbital-ordered NaO
Mizuki Miyajima, Fahmi Astuti, Takahito Fukuda +11
We have investigated the low-temperature magnetism of sodium superoxide (NaO), in which spin, orbital, and lattice degrees of freedom are closely entangled. The magnetic susc…
