Magneto-ionics allows for tunable control of magnetism by voltage-driven transport of ions, traditionally oxygen or lithium and, more recently, hydrogen, fluorine, or nitrogen. Here, magneto-ionic effects in single-layer iron nitride films are demonstrated, and their performance is evaluated at room temperature and compared with previously studied cobalt nitrides. [...]

28 p, 1.6 MB CoDiAJe - the Annotated Diachronic Corpus of Judeo-spanish : Description of a Multi-alphabetic Corpus and its Textual and Linguistic Annotations / Quintana, Aldina (The Hebrew University of Jerusalem)
Judeo-Spanish differs from late 15th-century Spanish and modern Spanish in several respects, such as its morphology, syntax, and semantics, but the most visible difference is in the alphabet. From the end of the 19th century, Judeo-Spanish has been written in various alphabets -Greek, Cyrillic, and especially Latin-. [...]
El judeoespañol se diferencia del español de finales del siglo XV y del español moderno en varios aspectos que afectan a la fonética y fonología, morfología, sintaxis y semántica. Sin embargo, la diferencia más fácilmente apreciable está en el alfabeto. [...]

14 p, 5.1 MB Reversible, electric-field induced magneto-tonic control of magnetism in mesoporous cobalt ferrite thin films / Robbennolt, Shauna (Universitat Autònoma de Barcelona. Departament de Física) ; Menéndez Dalmau, Enric (Universitat Autònoma de Barcelona. Departament de Física) ; Quintana Puebla, Alberto (Universitat Autònoma de Barcelona.

Departament de Física) ; Sort Viñas, Jordi (Universitat Autònoma de Barcelona. Departament de Física)
The magnetic properties of mesoporous cobalt ferrite films can be largely tuned by the application of an electric field using a liquid dielectric electrolyte. By applying a negative voltage, the cobalt ferrite becomes reduced, leading to an increase in saturation magnetization of 15% (M) and reduction in coercivity (H) between 5-28%, depending on the voltage applied (−10 V to −50 V).

18 p, 4.2 MB Electrolyte-gated magnetoelectric actuation : Phenomenology, materials, mechanisms, and prospective applications / Navarro Senent, Cristina (Universitat Autònoma de Barcelona.

Departament de Física) ; Pellicer Vilà, Eva Maria (Universitat Autònoma de Barcelona. Departament de Física) ; Sort Viñas, Jordi (Universitat Autònoma de Barcelona. Departament de Física)
Manipulation of the magnetic behavior of materials with voltage (i. e. , magnetoelectric actuation) has become a topic of intense research during the last years. Apart from its obvious interest from a basic science standpoint, control and eventual switching of the magnetization without applying any external magnetic field (or spin polarized current) has the potential to drastically reduce the power consumption of magnetic devices due to the lack (or minimization) of Joule heating dissipation effects.
