Modern paleomagnetic studies are often based on the measurement of rock samples in the centimeter range, as this size offers a good balance between handling, accuracy, and sufficient magnetic moment strength. However, natural rocks with complex geological histories often contain different generations of magnetization in the submillimeter range. For example, sedimentary rocks, including chondritic meteorites, can contain millimeter- or submillimeter-sized fragments with different magnetizations. In igneous rocks, small sub-areas may have more stable magnetizations than the surrounding material. Obtaining information about magnetic fields from such samples depends on the accurate measurement of the net moment. Due to their small size, many of these samples have net moments that cannot be detected with instruments commonly used in geology.
