Ricardo CSIC ORCID | Fecha de publicación: | 2013 | Editor: | American Physical Society | Citación: | Physical Review B 88: 214429 (2013) | Resumen: | Magnetization studies have been performed on a polycrystalline sample of Dy5Si3Ge as a function of an applied magnetic field (up to 50 kOe) and hydrostatic pressure (up to 10 kbar) in the 5-300 K temperature range. The anomalous behavior of the magnetic susceptibility indicates that a Griffiths-like phase exists at low magnetic fields and pressures up to 10 kbar. We present evidence that the high-temperature second-order ferromagnetic transition can be coupled with the low-temperature first-order crystallographic transformation into a single first-order magnetic-crystallographic transformation using a magnetic field and hydrostatic pressure as tuning parameters. The effect of pressure on the Griffiths-like phase is reported and analyzed in the framework of the complex competition between the interslab and intraslab magnetic interactions. © 2013 American Physical Society. | Descripción: | Under the terms of the Creative Commons Attribution License 3.0 (CC-BY).-- et al. | Versión del editor: | http://dx.doi.org/10.1103/PhysRevB.88.214429 | URI: | http://hdl.handle.net/10261/117561 | DOI: | 10.1103/PhysRevB.88.214429 | Identificadores: | doi: 10.1103/PhysRevB.88.214429 issn: 1098-0121 e-issn: 1550-235X |
