标题： Observing a quantum magnetic effect in CaYAl3O7-X particles (X=Ni, Fe, Co)

摘要： 钇钙铝酸盐，化学式为CaYAl3O7，由于在掺杂或共掺杂时具有显著的发光特性，已被广泛研究。 此外，它在高温下表现出优异的压电特性。 然而，通过掺杂或共掺杂这种材料可能获得的潜在磁性特性直到现在仍未被深入探索。 在本项创新研究中，我们研究了掺杂过渡金属如钴、铁和镍的钇钙铝酸盐颗粒的量子磁性特征。 我们的宏观尺度磁滞回线磁性测量揭示了文献中尚未记录的有趣的磁性特征。 鉴于该材料在生物微机电系统中的高适用性，我们进行了详细研究以证明这些发现。 显示英文摘要

摘要： Yttrium calcium aluminate, with the formula CaYAl3O7, has been extensively researched due to its remarkable luminescent properties when doped or co-doped. Additionally, it exhibits exceptional piezoelectric properties at high temperatures. However, the potential magnetic properties this material can acquire through doping or co-doping have largely gone unexplored until now. In this innovative study, we investigate the quantum magnetic characteristics of yttrium calcium aluminate particles doped with transition metals such as cobalt, iron, and nickel. Our magnetic measurements of hysteresis curves in the macroscopic regime reveal intriguing magnetic characteristics that have not been documented in the literature. Given the high applicability of this material in biological microelectromechanical systems, we conducted a detailed study to demonstrate these findings.
