Evaluation of magnetic behaviour and in vitro biocompatibility of ferritic PM2000 alloy
M. S. Flores,Gabriela Ciapetti,José Luis González-Carrasco,M. A. Montealegre,Marta Multigner,Stefania Pagani,G. Rivero +6 more
TL;DR: It is shown that PM2000 is a soft magnetic material irrespective of its material condition, its remanent magnetisation being very low (up to about 3% for the recrystallised swaged material).

Time dependence of electrical bioimpedance on porcine liver and kidney under a 50 Hz ac current.
TL;DR: The measurements show a correlation between the biological evolution and the electrical bioimpedance of the organs, which increases from its in vivo value immediately after excision, multiplying its value by 2 in a few hours.

Sensor system for early detection of heart valve bioprostheses failure
G. Rivero,J. M. García-Páez,L. Alvarez,Marta Multigner,J. Valdés,I. Carabias,J. Spottorno,Antonio Hernando +7 more
TL;DR: The aim of this work is to find a magnetic sensor, which could be integrated in a bioprosthesis, monitoring the prosthesis in such a way that allows to confidently forecast the failure, and characterizing the signal changes when the valve begins to fail, preventing the bioposthesis functional failure.
Interplay between the magnetic anisotropy contributions of cobalt nanowires
Jaime Sánchez-Barriga,Jaime Sánchez-Barriga,M. Lucas,Florin Radu,E. Martin,Marta Multigner,Pilar Marín,Antonio Hernando,G. Rivero +8 more
TL;DR: In this paper, the magnetic properties and the crystallographic structure of the cobalt nanowire arrays as a function of their nanoscale dimensions are reported. But no significant changes in the magnetic behavior were observed with decreasing temperature, indicating that the effective magnetoelastic anisotropy does not play a dominant role in the remagnetization processes of individual nanowires.
Magnetic and structural properties of electrodeposited CoNiP amorphous ribbons
TL;DR: The magnetic behavior of the material depends strongly on the Co/Ni ratio, ranging from paramagnetic to ferromagnetic as the Co content increases as mentioned in this paper, and the extrapolation for 100% Co content is very close to that of crystalline Co. Although the X-ray diffraction patterns indicate that the material is amorphous, the observed magnetic behavior suggests that the system is composed by nanocrystalline Co particles embedded in an ammorphous Ni P matrix.
