            Whenever the elastic energy of a solid depends on magnetic field, there is a magnetostrictive response. Field-linear magnetostriction implies piezo- magnetism and vice versa. Here, we show that Mn3Sn, a non-collinear anti- ferromanget with Weyl nodes, hosts a large and almost perfectly linear magnetostriction even at room temperature. The longitudinal and transverse magnetostriction, with opposite signs and similar amplitude are restricted to the kagome planes and the out-of-plane response is negligibly small. By studying four different samples with different Mn:Sn ratios, we find a clear correlation between the linear magnetostriction, the spontaneous magneti- zation and the concentration of Sn vacancies. The recently reported piezo- magnetic data fits in our picture. We show that linear magnetostriction and piezomagnetism are both driven by the field-induced in-plane twist of spins. A quantitative account of the experimental data requires the distortion of the spin texture by Sn vacancies. We find that the field-induced domain nucleation within the hysteresis loop corresponds to a phase transition. Within the hys- teresis loop, a concomitant mesoscopic modulation of local strain and spin twist angles, leading to twisto-magnetic stripes, arises as a result of the com- petition between elastic and magnetic energies.more » « lessFree, publicly-accessible full text available December 1, 2025

            Science, Technology, Engineering, and Mathematics (STEM) graduate education traditionally has focused on developing technical and research skills needed to be successful in academic and research settings. In the past decade, however, STEM graduate students increasingly have sought positions in the industry [1]; a recent study by Sherman et al. [2] found that non-academic industry jobs were the most preferred career choice for STEM doctoral students. Despite this preference, graduate education has yet to adapt to better prepare students for their industry positions; a significant portion of students need critical professional skills, such as project management (PM), needed to be effective leaders in these non-academic environments [3-9]. Although a required skill in the industry, these professional skills also can significantly enhance future careers within research and the academy.more » « less
