As star material, perovskites have been widely used in the fields of optics, photovoltaics,
electronics, magnetics, catalysis, sensing, etc. However, some inherent shortcomings, such …

Frustration in magnetic materials arising from competing exchange interactions can prevent
the system from adopting long-range magnetic order and can instead lead to a diverse …

This review is a study of how the idea of spin ice has evolved over the years, with a focus on
the scientific questions that have come to define the subject. Since our initial discovery of …

Fractals—objects with noninteger dimensions—occur in manifold settings and length scales
in nature. In this work, we identify an emergent dynamical fractal in a disorder-free …

Magnetically frustrated systems provide fertile ground for complex behaviour, including
unconventional ground states with emergent symmetries, topological properties, and exotic …

We test the fluctuation-dissipation relation (FDR) in spin ice materials Dy $ _2 $ Ti $ _2 $ O $
_7 $ and Ho $ _2 $ Ti $ _2 $ O $ _7 $ by measuring both the magnetic noise and the out-of …

Noise generated by motion of charge and spin provides a unique window into materials at
the atomic scale. From temperature of resistors to electrons breaking into fractional …

Neutron scattering, specific-heat, and magnetization measurements on both powders and
single crystals reveal that Dy 2 Ir 2 O 7 realizes the fragmented monopole crystal state in …

The Ising antiferromagnets on the triangular and on the pyrochlore lattices are two of the
most iconic examples of magnetic frustration, paradigmatically illustrating many exotic …

Direct detection of spontaneous spin fluctuations, or “magnetization noise,” is emerging as a
powerful means of revealing and studying magnetic excitations in both natural and artificial …
