Dipolar-driven mean-field criticality in the ferrimagnet Eu $_{2}$ MnSi $_{2}$ O $_{7}$

Masahiro Kawamata, Maxim Avdeev, Yusuke Nambu

We report mean-field critical behavior in Eu $_{2}$ MnSi $_{2}$ O $_{7}$ , a melilite-type ferrimagnet with spin-only Eu $^{2 +}$ and Mn $^{2 +}$ moments and negligible orbital contributions. Magn…

Symmetry-Protected Weyl Nodal Loops in a Triangular Altermagnet

Chao-Chun Wei, Xiaoyin Li, Sophia Adams +9

Weyl semimetals and altermagnets represent two distinct classes of quantum materials exhibiting nontrivial topological and magnetic order, respectively. Here we report the realizat…

Collinear Magnetic Structure in the Diamond Network Magnet EuTi $_{2}$ Al $_{20}$

Masahiro Kawamata, Ryuji Higashinaka, Takeshi Matsumura +5

The magnetic structure of EuTi $_{2}$ Al $_{20}$ , in which magnetic Eu $^{2 +}$ ions form a diamond network, was investigated using neutron and resonant X-ray diffraction on powder and si…
