We report on the quantum criticality of YbCu4Ni as revealed by our combined micro- and macro-measurements. We determine the crystal structure of YbCu4Ni with site mixing by neutron diffraction measurements, which suggests the possible presence of Kondo disorder. However, decreasing the local spin susceptibility distribution and the development of spin fluctuations below 10 K at ambient pressure by muon spin rotation and relaxation measurements suggests that YbCu4Ni exhibits quantum criticality. Therefore, our experimental results indicate that YbCu4Ni is a material that exhibits quantum criticality under zero magnetic field and ambient pressure.

In many industries, there is a growing demand for semiconductor pressure sensors capable of operating in harsh environments with extremely high and low temperatures and high vibrations. Utilizing the piezoresistive effect of heavily doped N-type 4H-SiC, we proposed a family design of eight pressure sensor chip structures featuring different diaphragm shapes of circles and squares, along with different piezoresistor configurations. The 4H-SiC piezoresistive pressure sensor was developed using micro-electromechanical systems (MEMS) technology and encapsulated in a leadless package structure via low-stress connection achieved by glass frit sintering. The 4H-SiC pressure sensor demonstrates impressive performance, exhibiting an accuracy of 0.18% FSO and a temperature tolerance range from −50 to 600 °C, with a temperature coefficient of zero output as low as 0.08%/°C at 600 °C. Furthermore, the developed sensor shows remarkable stability under conditions of high-temperature vibration coupling. The advancement of this family of 4H-SiC pressure sensors provides a promising solution for pressure measurement in harsh industrial environments. © The Author(s) 2025.

We present a systematic method to automatically generate symmetry-adapted magnetic structures for a given crystal structure and general propagation vector k as an efficient approach of the analysis of complex modulated magnetic structures. The method is developed as an extension of the generation scheme based on the multipole expansion, which was demonstrated only for the propagation vector k=0 [M.-T. Suzuki et al., Phys. Rev. B 99, 174407 (2019)]. The symmetry-adapted magnetic structures characterized with an ordering vector k are obtained by mapping the multipole magnetic alignments on a virtual cluster to the periodic crystal structure with the phase factor for the wave vector k. This method provides all magnetic bases compatible with irreducible representations under a k group for a given crystal structure and wave vector k. Multiple-k magnetic structures are derived from a superposition of single-k magnetic bases related to the space group symmetry. We apply the scheme to deduce the magnetic structures of α-Mn and CoM3S6 (M=Nb, Ta), in which the large anomalous Hall effect has recently been observed in antiferromagnetic phases, and identify the magnetic structures inducing anomalous Hall effect without net magnetization. The physical phenomena originating from emergent multipoles in the ordered phases are also discussed based on the Landau theory.
