| 英文摘要 | The interplay between superconductivity and magnetism is an important subject in condensed matter physics. EuFe2As2-based iron pnictides could offer an interesting plateau to study their relationship that has attracted considerable attention. So far, two magnetic phase transitions were observed in EuFe2As2-based crystal, which were deemed to originate from the itinerant Fe moments (similar to 190 K) and the localized Eu2+ moments (similar to 19 K), respectively. Here, we systematically studied the heat capacity for the EuFe2(As1-xPx)(2) crystals with x = 0.21 (optimally doped) and x = 0.29 (overdoped). We have found two new magnetic orders in the superconducting state (ranging from 0.4 to 1.2 K) in the optimally doped crystal. As more P was introduced into the As site, one of the magnetic orders becomes absent in the overdoped crystal. Additionally, we observed strong field and orientation dependence in heat capacity. The present findings in EuFe2(As1-xPx)(2) have detected the new low-temperature magnetic orders, which may originate from the localized Eu2+ spins order or the spin reorientation. |
