摘要：

Low-frequency magnetic properties of ferromagnetic composite wires were studied with and without coating by ferrofluid. Nonmagnetic CuBe wires of 0.1 mm diameter were electroplated with FeCoNi layer of 1 mu m thickness. Magnetization curves were measured in the frequency range of 10 Hz-3 kHz. The composite CuBe/FeCoNi/ferrofluid material shows a hysteretic behaviour in a small field. The hysteresis loop of ferrofluid covered electroplated wire is not a simple sum of the ferrofluid "wire" plus non-covered wire signals. It indicates an interaction between magnetic wire and ferrofluid which can be revealed by low-frequency measurements. The combination "electroplated wire/ferrofluid" can be considered as a new type of composite magnetic material consisting of solid magnetic core coated by complementary liquid magnetic material. Low-frequency measurements in presence of ferrofluid can be a useful method to study magnetic properties of ferromagnets. (C) 2005 Elsevier B.V. All rights reserved.
