A simple and unambiguous test has been recently suggested [J. Phys. D: Applied Physics, 52, 01LT01 (2018)] to check experimentally if a resistor with memory is indeed a memristor, namely a resistor whose resistance depends only on the charge that flows through it, or on the history of the voltage across it. However, although such a test would represent the litmus test for claims about memristors (in the ideal sense), it has yet to be applied widely to actual physical devices. In this paper, we experimentally apply it to a current-carrying wire interacting with a magnetic core, which was recently claimed to be a memristor (so-called `$\Phi$ memristor') [J. Appl. Phys. 125, 054504 (2019)]. The results of our experiment demonstrate unambiguously that this `$\Phi$ memristor' is not a memristor: it is simply an inductor with memory. This demonstration casts further doubts that ideal memristors do actually exist in nature or may be easily created in the lab.

忆阻器测试的实验演示

最近有人提出了一种简单而明确的测试方法[J．物理 D：Applied Physics，52，01LT01（2018）]，通过实验检查具有存储器的电阻器确实是忆阻器，即电阻器的电阻仅取决于流过它的电荷或取决于其两端的电压历史。但是，尽管这样的测试代表了关于忆阻器的主张的石蕊测试（从理想的意义上来说），但它尚未广泛应用于实际的物理设备。在本文中，我们将其实验性地应用于与磁芯相互作用的载流线，该磁芯最近被称为忆阻器（所谓的“ $ \ Phi $忆阻器”）。应用 物理 125，054504（2019）]。我们的实验结果清楚地表明，此“ $ \ Phi $忆阻器”不是忆阻器：它只是一个带有存储器的电感器。
