Model 10 VSM

 

Product Highlights:

The Model 10 VSM is the state of the art in VSM magnetometers. Its sensitivity surpasses the sensitivity of all other commercial VSMs. Its field range and resolution make it the ideal system both for high and low coercivity materials. The accuracy in the determination of the magnetization vector, together with the high sensitivity, makes this the first VSM that can be a real alternative to a torque magnetometer for anisotropy studies on modern recording materials.

 

Description

The Model 10 VSM is a computer-controlled measurement system capable of characterizing the widest variety in magnetic samples. Its accuracy, reliability, user friendliness and ability to measure low as well as high coercivity samples, and high as well as low moment samples make this the ideal all-around research instrument for magnetic research laboratories with the highest requirements. These features, combined with its speed of measurement and its ability to handle a wide range of sample shapes and sizes, make the Model 10 VSM the ideal measurement system for production environments as well.

The software supports all well-known magnetic measurements such as hysteresis and remanence loops, SFD, Delta M and Henkel plots, but also less known measurements such as Angular and AC remanence loops. Any series of measurements can be run without user intervention using the flexible software. The powerful data analysis software has many options including automatic subtraction of background signals and the calculation of up to 60 different test parameters.

The software has a research mode allowing for the largest flexibility in setting up measurements available on any commercial VSM. It also provides a production mode that gives access only to predefined measurement recipes for the less experienced user.

High Accuracy

The high precision stepped field control used in conjunction with digital signal averaging leads to increased accuracy of the measured data and measurement parameters, while at the same time facilitating measurements on soft magnetic materials with a field resolution of better than 0.01 Oe.

The high performance vector system allows for vector measurements with the same sensitivity and speed as scalar measurements, and with an accuracy in the determination of the magnetization vector of better than ± 1.5 % or ± 1.5°. This, together with its large field range, makes it the ideal instrument for research and development of modern high anisotropy recording materials.

High Field Resistive Magnet

This system allows for scalar, room temperature measurements up to 3 Tesla. This field range is better than anything achieved in a similar-sized resistive magnet system and is achieved without the very costly and cumbersome use of liquid helium, necessary in super conducting magnet systems. The liquid helium saved using a resistive rather than a super conducting magnet easily adds up to several thousands of dollars per year. Furthermore, the other problems associated with super conducting magnets such as high stray fields are eliminated as well.

Fast and Easy to Use

The sample loading system allows for very easy sample replacement within seconds rather than minutes.

The high-speed field control and the absence of large time constants in the signal electronics make it possible to do high speed measurements without sacrificing the accuracy of the data and critical parameters such as the coercive field.

The MR option measures the resistance of thin film samples as a function of both magnetic field, temperature and angle. The measurement can be completed in under two minutes even at high resolution.

Long Term Stability

A very accurate feedback system ensures that the Model 10 VSM is stable and reliable for long run measurements. Unlike AGFM systems, the detection principle does not influence the measured properties and this, together with the system's long term stability, makes it the ideal instrument for time decay experiments.
