Magnetic Fe@FeOx, Fe@C and α-Fe2O3 Single-Crystal Nanoblends Synthesized by Femtosecond Laser Ablation of Fe in Acetone

open access: yesNanomaterials, 2018
There are few reports on zero-field-cooled (ZFC) magnetization measurements for Fe@FeOx or FeOx particles synthesized by laser ablation in liquids (LAL) of Fe, and the minimum blocking temperature (TB) of 120 K reported so far is still much higher than ...

Experimental methods in chemical engineering: Magnetometry

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 10, Page 5176-5188, October 2026.
Abstract Magnetometry is a non‐invasive technique to characterize the behaviour of magnetic materials of which the most common contain Fe, Co, and Ni. Vibrating sample magnetometers (VSMs) vibrate samples at a fixed frequency in a static, homogeneous magnetic field to induce a voltage in pick up coils according to Faraday's law of induction.

Switching on antiferromagnetic coupled superparamagnetism by annealing ferromagnetic Mn/CdS nanoparticles

open access: yes, 2011
Mixed phases of metastable cubic and stable hexagonal manganese assisted CdS nanoparticles were synthesized by a colloidal route. These phases were quantified by the Short and Steward method of X-ray diffraction and differential scanning calorimetry ...

Cluster spin glass and superparamagnetism in RuSr2Eu1.5Ce0.5Cu2O10- (delta)

open access: yes, 2010
We investigate in detail the dc magnetization and nonlinear ac susceptibility behavior of the superconducting ferromagnet RuSr2Eu1.5Ce0.5Cu2O10- δ (Ru1222) to develop a comprehensive understanding of the spin glass and superparamagnetism in this material.

Mechanically Assisted Magnetic Actuation in Ceramic‐Based Microscrolls for Fast and Durable Soft Robotic Systems

open access: yesAdvanced Materials, Volume 38, Issue 52, 16 September 2026.
Ceramic‐based V2O5/Fe3O4 hybrid films are shaped into butterfly‐proboscis‐inspired microscroll actuators. Magnetic triggering initiates unrolling, while geometry‐programmed elastic strain energy drives rapid recoil, enabling fast, reversible, durable, and load‐bearing actuation under near‐field magnetic stimulation.

Superparamagnetism in Heterogeneous AgFe Thin Films - A Low Energy μSR Study

open access: yes, 2001
This paper describes a study of superparamagnetism in iron nanoclusters using low energy muSR, including for the first time zero field measurements, which yield an intrinsic nanocluster superparamagnetic relaxation rate of nu(0) = 67 +/- 15 MHz and an ...
