In quantum materials, degeneracies and frustrated interactions can have a profound impact
on the emergence of long-range order, often driving strong fluctuations that suppress …

Altermagnets (AM) are a recently discovered third class of collinear magnets, distinctly
different from conventional ferromagnets (FM) and antiferromagnets (AF). AM have been …

Ultrafast interaction between the femtosecond laser pulse and the magnetic metal provides
an efficient way to manipulate the magnetic states of matter. Numerous experimental …

We have experimentally studied the accuracy of the Jones-type reflection matrix R that
describes light reflection from a magnetic sample exhibiting the magneto-optical (MO) Kerr …

Excitation by a femtosecond laser pulse is an efficient method to control various ultrafast
spin manipulation processes, eg, ultrafast demagnetization, remagnetization, and damping …

We report the investigation of spin dynamics in the antiferromagnetic metal EuIn 2 As 2 with
the Zintl phase by using time-resolved magneto-optical Kerr effect (TR-MOKE) and transient …

We demonstrate a spectral shift in the peak frequency of terahertz (THz) emission by
ultrafast laser-induced demagnetization in the Fe 20 Ni 80 (Py) film. Experimentally, red …
